ELEVATOR-BIN.

QPECIFECA'IION forming part of Letters Patent No. 745,017, datedNovember 24, 1903.

' Application filed August 28, 1900. Serial No. 28,365. (No model.)

To all whom it may concern.-

Be it known that I, JAMES ALEXANDER JAMIESON, mechanical engineer, ofthe city of Montreal, Province of Quebec, Canada, have invented certainnew and useful Improvements in Elevator-Bins;.and I do hereby declarethat the following is a full, clear, and exact description of the same.

The invention relates particularly to elevator-bins of the typeillustrated and described in my pending application filed on the 27th ofAugust, 1900, under Serial No. 28,254, and may be said briefly toconsist of a hopper-like bin-bottom comprising an open rectangular mainframe suspended from and below the level of a series of inclosingstringers by a series of metallic strips connected at their ends to thestringers and taking beneath the said main frame. The walls of saidhopper-like bottom are formed by a series of diagonal rails secured attheir ends to said stringers and frame and a lining extending over saiddiagonal rafters, while an inverted truncated conical section is hungfrom the inner edges of said main frame and is provided with a slidingvalve.

For full comprehension, however, of my invention reference must be hadto the accompanying drawings, forming a part of this specification, inwhich like symbols indicate the same parts, and wherein-- Figure l is aplan view of two of a series of bins constructed according to myinvention and partly in horizontal sectional view.

Fig. 2 is a vertical sectional view thereof,

taken on line A B, Fig. l; and Fig. 3, a similar view to Fig. 2, takenat right angles thereto. Fig. 4 is a perspective view illustrating theframe for supporting the lower end of the bin-bottom.

The main frame consists of four beams b and c, secured togetherin theform of a square by cutting two, 1), thereof shorter than the other two,0, and arranged with the beams 19 at right angles to and between thebeams 0, while the ends 6 thereof are cut on an incline to rest ininclined notches in the inner sides of the beams c, and a pair ofboltsfsecure all four beams together. This rectangular frame issuspended from a series of stringers 70 by means of four metallic stripsZ, extending along the under sides of the beams 17 and secured at theirends to the top of said stringers by preferably bending the ends thereofto take over the adjacent ends of a pair of spaced hard-wood strips m,where they are fastened and held in place by a wedge 12 and the weightof the superstructure, while the strips are held against lateraldisplacement by nails or screws 0 taking therethrough into thestringers.

A series of diagonal rafters p are secured at their lower ends to thetops of the beams 12 and at their upper ends to the cribbing 'r of thebin, the base only whereof is shown, as it may be of ordinaryconstruction. Alining s, of Wood, metal, or other material, extendsacross these diagonal rafters and completely covers the spacestherebetween.

A metallic inverted truncated conical end piece u is secured at its baseby nails tor-otherwise to rails 22 upon the inside faces of the beams band has a pair of guideways w for a slide-valve 00 under the control ofa lever 11 The hopper-like bottoms are preferably supported uponcolumns, (indicated at 2.)

Hopper bottoms constructed according to my invention are light inweight, and, besides being more durable, take up less space and materialin being hung than have been necessary heretofore to secure the hopperbottoms formerly used in place.

What I claim is as follows:

1. In combination with a bin, of a suspended bottom therefor consistingof an open frame of less area than the lower end of said bin; means forsupporting said open frame; a series of diagonal rafters extending fromsaid open frame to the lower end of said bin, a lining for saidhopper-like bottom, and means for opening and closing the lower end ofsaid bottom substantially as described and for the purpose set forth.

2. In combination with the lower end of an elevator-bin, of a suspendedbin-bottom consisting of an open rectangular frame of less area than thelower end of said bin; a series of metallic strips each connected at itsends to opposite sides of the lower end of said bin and extending underone side of said rectangular frame; a lining extending from said frameto said bin-bottom, means for supporting said lining; means for openingand closing the lower end of said bottom, substantially as described.

3. In combination with the lower end of an elevator-bin, of a suspendedbin-bottom consisting of an open rectangular frame of less area than thelower end of said bin; a series of metallic strips each connected at itsends to opposite sides of the lower end of said bin and extending underone side of said rectangular frame; a series of rafters extendingdiagonally from said frame to the lower end of said bin; a liningextending over said rafters from said frame to said bin -bottom, meansfor opening and closing the lower end of said bottom, substantially asdescribed.

4. The combination of a series of stringers arranged in the form of asquare; means for supportingsaid stringers; a rectangular frame of lessarea than and located beneath the space inclosed by said stringers andwith its sides parallel to, said stringers; a series of metallic stripseach extending beneath and supporting one side of said rectangular frameand having its ends connected to the stringers parallel thereto; aseries of rafters extending diagonally from said frame to saidstringers; a lining extending over said rafters and from said frame tosaid stringers; and means for opening and closing the open end of saidhopper-like bottom substantially as described and for the purpose setforth.

5. The combination of a series of stringers arranged in the form'of asquare; means for supporting said stringers; arectangularframe of lessarea than and located beneath and with its sides parallel to saidstringers; a series of metallic strips each extending beneath andsupporting one side of said rectangular frame and having its endsextending to the onally from said frame to said stringers; a liningextending over said rafters and from said frame to said stringers;andmeans for opening and closing the open end of said 'ing diagonallyfrom said frame to said stringers; a series of metallic plates extendingover said rafters and covering the spaces therebetween; a liningextending over said plates and from said frame to said. stringers; andmeans for opening and closing the open end of said hopper-like bottom,substantially as described and for the purpose set forth.

7. The combination of a series of stringers arranged in the form of asquare; a rectangular frame of less area than and located beneath andwith its sides parallel to said stringers; a series of metallic stripseach extending beneath and supporting one side of said rectangular frameand having its ends connected to the stringers parallel thereto; aseries of rafters extending diagonally from said frame to saidstringers; a concrete lining extending over said rafters and from saidframeto said stringers; a metallic inverted truncated conical end piececonnected at its base to the inside edges of said rectangular frame; anda valve for opening and closing the open end of said inverted truncatedconical end piece, substantially as described and for the purpose setforth.

In testimony whereof I affix my signature in presence of two witnesses.

JAMES ALEXANDER JAMIESON.
